To all whom it ma concern:

Be it known that RALEIGH B. BUzzAmo,

a citizen of the United States, and resident of lVash-ing'ton, in the District of Columbia, have invented a new and useful Coin-Controlled Locker-Lock, 'of which the following erty to remove the key from the lock, to

constitute his check.- By use of the key he can unlock the locker again and take out his belongings, the key then being locked in the lock against theft or loss.

An' object of the invention is to av o1d patrons losing their money by dropping coins in the locks of lockers which are in use, and also to prevent fraudulent operation of the lock bya wire or the like, so. as to lock the locker without payment of a coin. To this end means are provided whereby closing of the door closes the coin entrance of the'lock, this being most simply and advantageously accomplished by placing a projecting lip on the door in position to cover'the coin-entrance, so as to prevent introduction either of acoin or a tool as long as the door is closed.

A further object is to avoid possibility of the user losing his coin and his service by operating the lock after deposit of the coin but before closing the door. For this purpose an arrester has been devised, which cooperates with the coin-drop, chute or passage, of the lock, to sustain the coin before reaching the instrumentality which acts upon it or through it to cause projection of the bolt, this arrester being displaced by the closing of the door, and preferably by the action of the same lip which blanks the coin-entrance. Thus. the user places his property in the open locker, drops a coin in the lock, and thereafter closes the door, whereupon, and not until then, the lock is rendered operative. The closing of the door also closes the coin-entrance, so that the coin must be introduced first; and as there is a natural tendency for the user to 'attempt to operate the lock as soon as he has given up his coin, the result would in many instances be a loss if it were not for th Specification of Letters Patent.

present rovision which makes it im ossible for im to operate the lock until the door is shut.

4 In the accompanying drawings forming a part hereof:

Figure 1 is a front elevation of a locker and lock, showing how the door-lip closes the coin-entrance and represses the coinarrester;

Fig. 2 is a front elevation of the lock on a larger scale; v

Fig. 3 is arearelevation ofthe lock in the unlocked condition, with the cover of. the coin-disk casing partly broken away, indicating two positions of the coin, arrested in the coin-drop above the coin-disk, and seated in the pocket of the disk, respectively;

Fig. 4 is a horizontal section on the line 44 of Fig. 2, showing the coin-arrester in Fig. 5 is a similar section, showing the condition with the coin-arrester displaced by the door-lip.

The general lock construction in which the present invention is shown embodied is the invention of another, and is illustrative of the combination, the invention being ap plicable, however, to other forms and types of coin-controlled lockerlocks.

The front plate or escutcheon 1 has a knob 2, a coin-entrance 3 and the key-slot end of a key-cylinder 4 on its outer side. key-cylinder and its cylinder-casing 5. constitute a well-known form of lock unit, containing tumbler arrangements-whereby the key can be removed in the locking tion only, and is locked in thelock by the tumblers when the lock is open. These matters being familiar require no illustration.

A swinging bolt 8 is pivoted at 11,, and is projected by a spring 17 The bit 14 of the key-cylinder cooperates with a recess or socket 15 in the rear-portion of the bolt. A bell-crank detent is pivoted at 19 and its rearwardly extending arm is formed with a primary holding shoulder 21, which cooperates with a projection 23 on the bolt to hold the latter in its fully retracted condition, the detent having a spring 24 whereby it engages automatically.

The contact extremity of the downwardly.

extending arm 26 of the detent is arranged to be encountered by a com a carried by a This condirotary coin-disk 30 having an eccentric coinpocket 31. The disk is connected to the knob 2 on the outside, and receives the coin from a coin-drop 2-9 on the inside leading from ing thereby locked in the cylinder until the next checking operation.

Coming now to the more particular novelty of the present invention, a lip 46 will be observed, which is fixed to the free edge of the door 47, of suchproportions and arrangement as to cover completely and closely the coin-entrance 3 in the front plate'l of the lock, and overlap adjoining portions of the plate. With this lip in closed position, it is impossible to introduce a coin or any other object into the coin passage and thence into the'interior of the lock. Thus an inattentive person cannot lose a coin in the lock of a locker which is in use; nor can the service of the locker be obtained without cost by placing articles in it, closing the door and then displacing the detent 18 by a Wire inserted through the coin-drop.

Further safeguard is afl'orded by a movable coin-arrester 48 having a portion 49, which blocks the coin-drop or path sufliciently to sustain a coin above the coin-mechanism,-in this instance above the disk 30.

.Such coin-arrester may have numerous forms and arrangements. In the particular construction illustrated it is a transverse arm in the interior of the lock, pivoted at one end to a lug 50, bent out of the wall of the coin-drop and having a finger 51 projecting outward through an opening 52 in the plate 1, in position to be struck and repressed by the lip 46 on the door. Other specific forms of operating connection may be employed whereby the door lip acts through an opening in the lock to displace the auxiliary. part. The coin-contacting portion 49 of the arrester may be a corner or jog on the arm 48, as shown, which normally stands in a notch 60 in the inner side portion of the lower end of the coin-drop.

Thevm'ember 48 is urged to and normally held in coin-arresting position by a spring 53. Closing of the door, therefore, not only blanks the outer coin-entrance but also clears the interior coin-passage above the coinmechanism, so that the coin may then reach the latter, enabling the lock to be actuated.

The same member 48 is illustrated as having another portion 54 which engages with the detent to hold the same against premature operation; this, however, forms part of the subject-matter of a separate application.

What I claim as new is:

1. The combination. of a coin-controlled look, a coin-entrance thereto, a relatively movable door subject to said lock, and a lip on the door for closing said. coin-entrance.

2. The combination of a coin-controlled.

lock comprising a spring-shot bolt, key-operated means controlling the unlocking of the bolt, a detent for holding the bolt in unlocked position, and knob-operated coin 'means for releasing the detent, a coin-en- 4. The combination of a coin-controlled lock having a bolt, coin means controlling the locking of the bolt, and key-operated means controlling the unlocking of the bolt, a coin-drop, a movable coin-stop in the drop, a door movable relatively to the lock and subject thereto, and means whereby closing of the door displaces said coin-arrester.
